At the Profession of Faith the new convert first recites the Apostles' Creed, being the historic symbol of Faith professed by countless converts throughout the centuries. Next is said,
I believe that seven Sacraments were instituted by Jesus Christ for the
salvation of mankind, namely, Baptism, Confirmation, Holy Eucharist,
Reconciliation, Anointing of the Sick, Holy Orders and Matrimony. I believe that the Pope, the Bishop of Rome, is the vicar of Jesus Christ on earth, that he is the supreme visible head of the whole Church and that he teaches infallibly what we must believe and do to be saved. I also believe everything which the holy Catholic, Apostolic and Roman Church defines and declares we must believe. I adhere to her with all my heart and I reject every error and schism which she condemns.
But, it also makes me wonder: why are there so many Catholics, mostly those baptized as infants, who at best take these Truths for granted and at worst repudiate them. What went wrong in their lives to lead to such a state of affairs within the Church? Ultimately, only God knows who is to blame. But the blame doesn't really matter. What matters is from this moment on that each and every sincere and faithful Catholic does what they can to correct the problem. Therefore let us learn our Faith and never hesitate to profess it both in the Church and in the world.
